We consider the contribution of changes in mortality and fertility to availability of living mothers and living children among older people in Britain, Finland and France. The proportion of people aged around 60 with a mother alive will more than double between those born in 1911 and 1970 before starting to decline slightly. Conversely, a higher proportion of elderly people are likely to have a surviving child than for any generation ever born in all three countries in the next quarter century or so, with about 85% of 80-year-old women having at least one surviving child, and about two-thirds having two or more.  相似文献

This article offers a preliminary analysis of the work environment of the national Church of Sweden. Previous research on this topic has been limited and has focused on either structural problems or leadership. This explorative study examined psychosocial work environment factors (those related to the interplay of physical, mental, organizational, and social conditions in the workplace) in the Church of Sweden and used a top‐down perspective. Data including documents and interviews and were analyzed and categorized in order to identify patterns of relevance for the psychosocial work environment in the organization. The results show four themes: unclear organization structure, a sense of being different, stressful work conditions, and a destructive communication style. The psychosocial work environment within the church is complex, characterized by deep conflicts that are often not dealt with.  相似文献

Autonomous vehicles (AVs) have the potential to improve the health and well-being of older people. This exploratory study involved in-depth interviews with 43 key stakeholders across a broad range of sectors to identify the primary policy implications of AVs for aging populations. Four main issues were evident: a general lack of salience of the needs of older people in the AV discourse, the perceived dominance of the commercial drivers of AV technology, the implications of the particular characteristics of the senior segment, and a lack of available analyses to guide decision making. Threats and opportunities represented by these issues are discussed.  相似文献

Socioeconomic vulnerabilities put adolescents at risk for mental wellbeing issues, also in times of a pandemic. In the present longitudinal online survey study, we explored changes in mental wellbeing (i.e., mood and life satisfaction) during the COVID-19 pandemic. Second, we examined how socioeconomic hardship in online home schooling predicted adolescents’ mental wellbeing 1 year later. Third, we tested whether this relation was mediated by feelings of uncertainty about the future. Fourth, we tested whether this relation was moderated (in terms of a protective factor) by self-efficacy. In total, 177 Dutch-speaking adolescents aged 10–18 years (Mage = 15.64, SDage = 1.72, 79% females) participated in all three 6-month separated waves (T1 = May 2020, T2 = November 2020, and T3 = May 2021). Mood results demonstrated that feelings of vigor decreased between T1 and T2, and feelings of tension and depression increased between T1, T2, and T3. Socioeconomic hardship in online home schooling in the early phase of the pandemic was negatively associated with both baseline mental wellbeing and 1 year later. Socioeconomic hardship at T1 predicted higher feelings of future uncertainty at T2, and higher levels of future uncertainty were associated with lower feelings of vigor, and higher feelings of tension and depression at T3. However, we found no evidence for mediation or moderation effects. In conclusion, the present findings illustrate the complexity of disentangling the adverse effects of socioeconomic hardship on adolescent mental wellbeing.  相似文献

Many children with aggressive behavior problems also suffer from anxiety. This cooccurrence may perhaps be explained by transdiagnostic factors. Identifying these factors seems crucial, as they may be important targets to treat these cooccurring problems effectively. This two-study paper investigates whether hostile interpretation of others’ intentions is a transdiagnostic factor for cooccurring aggression and anxiety problems, examining two samples of boys in middle childhood. We assessed boys’ aggression and anxiety using teacher-report in Study 1 (N = 84, Mage = 10.10), and parent-report in Study 2 (N = 115, Mage = 10.55). In both studies, we assessed hostile interpretation using vignettes describing ambiguous provocations by peers. Both studies revealed a strong association between aggression and anxiety problems, underscoring the necessity to examine factors that can explain this cooccurrence. However, in neither study was this association reduced when we added hostile interpretation to the model, suggesting that hostile interpretation did not function as a transdiagnostic factor in our samples. One possible explanation for these findings is that hostile interpretation predicts both aggression and anxiety problems, but in different children. We, therefore, encourage scholars to conduct more research to explain the high comorbidity of aggression and anxiety problems in children. Future research should also examine hostile interpretation as predictor or transdiagnostic factor for aggression and anxiety problems in more diverse population, including girls and other age groups.  相似文献

One of the important objectives of supply chain S&OP (Sales and Operations Planning) is the profitable alignment of customer demand with supply chain capabilities through the coordinated planning of sales, production, distribution, and procurement. In the make‐to‐order manufacturing context considered in this paper, sales plans cover both contract and spot sales, and procurement plans require the selection of supplier contracts. S&OP decisions also involve the allocation of capacity to support sales plans. This article studies the coordinated contract selection and capacity allocation problem, in a three‐tier manufacturing supply chain, with the objective to maximize the manufacturer's profitability. Using a modeling approach based on stochastic programming with recourse, we show how these S&OP decisions can be made taking into account economic, market, supply, and system uncertainties. The research is based on a real business case in the Oriented Strand Board (OSB) industry. The computational results show that the proposed approach provides realistic and robust solutions. For the case considered, the planning method elaborated yields significant performance improvements over the solutions obtained from the mixed integer programming model previously suggested for S&OP.  相似文献
